Common mistakes to watch for

These are mistakes children often make in this class, with a simple way to correct each one.

1000 is 'one and zero and zero and zero', four separate things rather than one thousand.: Bundle ten hundreds and count the bundle as 'one thousand'. Say '1 thousand, 0 hundreds, 0 tens, 0 ones'. (Numbers up to 9999)
When adding, start from the left (thousands) instead of the right (ones).: Always start from the ones column because regrouping affects the next column to the left. (Addition and Subtraction)
Multiplication always makes numbers bigger.: Show that 1 × 5 = 5 (same) and 0 × 5 = 0 (smaller). (Multiplication)
Division always makes numbers smaller.: Show that 12 ÷ 3 = 4, and 4 is smaller than 12, but also show 12 ÷ 1 = 12 (dividing by 1 doesn't change). (Division)
Any part of a shape is a fraction, even if parts are not equal.: A fraction must have equal parts. Show a shape with unequal parts and ask if it's fair. (Fractions)
Any line from one edge to another is a diameter.: Show a chord that is not through the centre and explain it is not a diameter. (Circles, Corners and Shapes)
Any shape that looks nice is symmetrical.: A shape is symmetrical only if you can fold it so both halves match exactly. (Symmetry and Patterns)
Using 'cm' for long distances like a road.: Show a metre scale and a map; explain that a road is many metres, so we use km. (Length, Weight and Capacity)

A 10-minute daily routine

Short, regular practice is easier to keep up than a long weekend session. One routine that fits into a busy evening:

Minutes 1–2, warm-up: ask one quick question aloud (see the list below) and let your child explain how they got the answer.
Minutes 3–7, learn: do one short lesson part on MangoMindz: the picture lesson is read aloud, then a quick check.
Minutes 8–9, use real things: repeat the idea with coins, spoons, rotis, a ruler or the clock at home.
Minute 10, reflect: ask “What was tricky today?” and look at one common mistake from this guide together.

Try this at home

Numbers up to 9999: Bundle 10 hundred-blocks into a thousand-cube and record 1000
Addition and Subtraction: Add 3456 + 2789 in columns: 6 + 9 = 15, write 5 and carry 1 to the tens; repeat for each column
Multiplication: Skip count in 7s to find 6 × 7: 7, 14, 21, 28, 35, 42
Division: Share 12 sweets among 3 friends
Fractions: Fold a paper strip into 2 equal parts, shade one part, write 1/2
Circles, Corners and Shapes: Name the parts of a circle drawn round a bangle: the centre is the middle point, a radius goes from the centre to the edge, a diameter goes edge to edge through the centre

Quick questions to ask aloud

Ask one a day. Let your child answer before you open the answer.

How many hundreds make one thousand? (10 / 100 / 1)
Show answer
Count the hundred-blocks: 100, 200, 300 ... 1000. Ten hundreds make one thousand.
True or false: When adding 4-digit numbers, we always start from the ones column.
Show answer
True. Yes, we start from the ones column because regrouping affects the next column to the left.
What is 7 × 8? (56 / 54 / 48 / 64)
Show answer
7 × 8 means 7 groups of 8. Skip count: 8, 16, 24, 32, 40, 48, 56. So the product is 56.
Riya has 12 sweets and shares them equally among 3 friends. How many sweets does each friend get? (4 / 3 / 6 / 9)
Show answer
12 sweets shared among 3 friends means 12 ÷ 3 = 4. Each friend gets 4 sweets.
Which shape shows one half shaded? (A circle divided into 2 equal parts, 1 shaded / A rectangle divided into 3 equal parts, 1 shaded / A square divided into 4 equal parts, 1 shaded)
Show answer
A circle divided into 2 equal parts, 1 shaded. One half means the whole is divided into 2 equal parts and 1 part is shaded.

Key words this year

thousand: 10 hundreds put together. We write it as 1000.
place value: What a digit is worth because of where it sits: thousands, hundreds, tens or ones.
regroup: To trade 10 ones for 1 ten, or 10 tens for 1 hundred, and so on.
estimate: To find a close answer without calculating exactly.
multiplication: A quick way to add the same number many times. 4 × 3 means 4 groups of 3.
product: The answer you get when you multiply. In 4 × 3 = 12, the product is 12.
division: Sharing equally or grouping into equal parts.
divide: To split into equal groups.
fraction: A part of a whole or a part of a group, written like 1/2.
numerator: The top number of a fraction; it tells how many parts we are talking about.
circle: A round shape where every point on the edge is the same distance from the centre.
centre: The exact middle point of a circle.

What mistakes do Class 4 children make in Maths?

1000 is 'one and zero and zero and zero', four separate things rather than one thousand. Fix: Bundle ten hundreds and count the bundle as 'one thousand'. Say '1 thousand, 0 hundreds, 0 tens, 0 ones'. (Numbers up to 9999) When adding, start from the left (thousands) instead of the right (ones). Fix: Always start from the ones column because regrouping affects the next column to the left. (Addition and Subtraction) Multiplication always makes numbers bigger. Fix: Show that 1 × 5 = 5 (same) and 0 × 5 = 0 (smaller). (Multiplication)

How much time should a Class 4 child spend on Maths at home?

About 10 minutes on most days is a good start: a quick warm-up question, one short lesson part and a minute to talk about what was tricky. Short, regular practice is easier to keep up than long sessions.
